! Slew rate greater than The Trek Model 10/10B-HS is a DC stable high-voltage power amplifier capable of precise control of output voltages in the range of 0 to ±10 kV DC or peak AC with an output current range of 0 to ±10 mA DC or 40 mA peak AC for 1 ms. The Model 10/10B-HS is configured as a noninverting amplifier with a fixed gain of 1000 V/V. Industrial and R&D applications include AC or DC biasing, atmospheric plasma, dielectric barrier discharge, electroactive polymers (EAP), electrophoresis, electrophotography, electrorheological fluids, electrostatic deflection, electro-optic modulation, ferroelectric material characterization, ion beam steering, mass spectrometers, material poling and particle accelerators. The Model 10/10B-HS features an all-solid-state design for high slew rate, wide bandwidth and low-noise operation. The fourquadrant, active output stage sinks or sources current into reactive or resistive loads throughout the output voltage range. This is essential for achieving the accurate output response and high slew rates demanded by reactive loads. The Model 10/10B-HS is protected against over-voltage and overcurrent conditions that may be generated by active loads or by output short circuits to ground.

Current Monitors Provide Low-Voltage Representations of the 10/10B-HS Output
Precision voltage and current monitors provide low-voltage representations of the high-voltage output and load current for monitoring purposes, or for use as feedback signals in a closed-loop system. The remote high voltage on/off feature provides a connection for a remote device to turn on and off the high-voltage output. This makes the Model 10/10B-HS suitable for automated or computercontrolled systems. The Model 10/10B-HS can be operated on a bench top or in a standard 19-inch rack.

Model 10/10B-HS Specifications All specifications are with no load unless otherwise noted.
Output Output Voltage Range 0 to ±10 kV DC or peak AC. Output Current Range 0 to ±10 mA DC or ±40 mA peak for 1 ms. (See Automatic Power Limit feature for limitations.)
Amplifier Input Input Voltage Range 0 to ±10 V DC or peak AC. Input Impedance 20 kW , nominal.
Features High-Voltage On/Off Switch selectable for either local or remote control. Local Individual push-button switches. Remote A TTL compatible input. A TTL high (or open) turns off the high-voltage output. A TTL low turns on the highvoltage output. Dynamic Adjustment A graduated one-turn panel potentiometer is used to optimize the AC response of the Model 10/10B-HS for various load parameters. Current Limit/Trip Switch selectable for either limit or trip. A graduated one-turn panel potentiometer is used to adjust the limit or trip level from 0 to ± 10 mA. Out of Regulation Status Indicator and Connector An indicator will illuminate and a BNC will provide a TTL low when the Model 10/10B-HS fails to produce the required high-voltage output such as during current limit. Fault/Trip Status Indicator and Connector An indicator will illuminate and a BNC will provide a TTL low when the high-voltage is disabled due to the set current trip level being exceeded or the internal interlock circuit being interrupted, such as by removal of the cover. This BNC connector will also provide a TTL low when the amplifier is out of regulation for more than 500 ms, such as during a current limit. However, in this instance the high-voltage output is not disabled. Voltage Monitor A buffered output provides a low-voltage replica of the high voltage output.
